Which should you buy?
The GT 7 Pro edges ahead on the Mars Score (73.2 vs 70), but the 3.2-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the GT 7 Pro if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. The biggest gaps in its favor are ram, wired charging, battery capacity, among others.
Pick the Xiaomi 15 if you photograph or shoot video regularly and want the better imaging pipeline of the two. Its strongest claims are front camera, weight, pixel density.
Both ship with comparable main camera, refresh rate, 5g support, so those specs don't separate the two — focus on the differences below.
Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity tells you both are well-rounded; the differences are about trade-offs, not quality.
